28、where significant. Tests shall be conducted as follows: 4.2.4.1 Assay. Weigh 0.2000 to 0.2200 g of specimen which has been previ- ously dried at 104“ + 2OC into a 250-milliliter (mL) beaker. Treat with 1 to 3 sulfuric acid and siinmer until all traces of hydrogen evolution are gone and the solution
29、is clear and free of all solids. Maintain the volume at approxi- mately 100 mL. Wash out a Jones reductor (see 6.5) with 50 mL of 1 to 19 sul- furic acid at a uniform rate requiring 5 to 10 minutes for passage. Leave sufficient solution in the reductor to cover the zinc. Collect the washings in a 1-
30、liter (L) flask containing 100 mL of ferric ammonium sulfate solution (345 g of ferric ammonium sulfate dodecahydrate diluted to 1 L with 2N sulfuric acid). These washings should require no more than 1 or 2 drops f 0.1N potas- sium permanganate solution to obtain a pink color. specimen solution at a
31、 uniform rate requiring 10 minutes for passage. Take care to keep the tip of the reductor below the surface of the liquid in the flask to prevent oxidation of the titanium. .Wash with 100 mL of 1 to 19 sulfuric acid. Follow with 100 mL of water. Make sure that the reductor is always filled with solu
32、tion or water to the upper level of the zinc. Titrate the contents of the flask with standardized 0.1N potassium permanganate solu- tion (see 6.6) to the appearance of a light pink color that persists for 30 seconds. A few milliliters before the end point, add 5 mL of o-phosphoric acid to improve en
33、d point detection. Calculate the percent by weight titanium as follows : Follow this by adding the 4.79AB W Percent titanium = where: A = Milliliters of standardized potassium permanganate solution used, B = Normality of the standardized potassium permanganate solution, and C = Weight of specimen in
34、 grams. 4.2.4.2 Burning time. Dry the specimen to constant weight at 104“ + 2C. Place sufficient dried specimen in a kraft paper laminated tube, closed on one end, 10 inches long, 0.328 - + 0.006 inch inside diameter, and 0.440 + 0.008 inch outside diameter (see 6.7). the powder.
